Wow, I really appreciate such expert help. Thank you all very much.

I installed the new monovalve solenoid this afternoon. This evening's drive home will reveal how successful I was.

That's interesting that it opens/closes so often. Most cars I've worked on it's either open or shut. I guess that's why they went for a solenoid instead of a vacuum pod.

As for the air coming from weird vents, it's intermittent and difficult to put a finger on. I am betting either the vacuum pods, or the CCU. I've seen other posts where people talk about bad solder joints inside the CCU. Does that apply to my car, or is that a different version of the CCU? I am quite handy with a soldering iron and good at getting small things apart.

If this was your problem to fix, which would you check first? Which is less of a pain to get at?


Thanks again for all the great help.
